Deansteel Manufacturing fabricates a
complete line of independently tested bullet and blast
resistant doors, frames, & windows to suit your security
needs. Our bullet resistant products have been tested to
all threat levels set forth by UL-752, NIJ 0108.01, and ASTM
F-1233. While most of the time we custom manufacture these
products to meet project requirements, we also offer a number
of ballistic and blast resistant door assemblies as “stock”
items, allowing us to ship directly from our warehouse to you
immediately.

This innovative product line is backed up by Deansteel’s
commitment to the highest quality products, attentive customer
service, and “small business-style” relationships that have
served as the building blocks for this family owned business
for over 50 years.

Deansteel has also expanded our existing line of security
products to include blast resistant door assemblies and fixed
windows. We now offer the following new solutions to
challenging security demands:

Blast doors and frame assemblies to withstand peak blast
pressures up to 50 psi and a wide range of blast durations.

Deansteel Manufacturing Company first ventured into the sheet metal business
in 1856 when Joseph
Dean, the great-great uncle of Company owner, John Dean, learned the
craft of sheet metal working as an Indentured Apprentice issued by the
Crown of England. After completing his apprenticeship, Joseph and his
wife immigrated to Texas and set up shop in San Antonio. His primary
business consisted of fabricating common steel household items like pots
and pans, rain gutters, and stove pipes to name a few. The Dean name
quickly earned a reputation throughout South Central Texas as a mark
of quality workmanship.

At the close of World War II, Albert Dean, Jr. returned to San Antonio
from his service in the US Navy, and through hard work and determination
acquired the old sheet metal shop on South Flores Street started by his
great uncle, and founded what is known today as Deansteel Manufacturing
Company.

Deansteel’s first job was to manufacture doors and frames for the
Laredo, Texas Hospital. The entire order was manufactured on a single,
four foot, manually operated press brake; and the job was delivered on
time! This was the start of our Hollow Metal division and for the next
decade Deansteel focused on manufacturing high-quality, commercial duty
steel doors and frames.

In 1969, Livingston Shipbuilding, located in Orange, Texas, asked Deansteel
if we could provide them with Marine doors, frames, and wall trim durable
enough for duty on offshore drilling rigs. We said yes, and Deansteel’s
Marine Division was born. What started out as one custom job grew into
an entire division of marine products.

Over the years, the company owner, John Dean, saw a worldwide need
for more specialized security products and branched out to start Deansteel
BRP, Bullet Resistant Products Division.
This is our newest division but is already expanding with the inclusion
of Blast Resistant Products; and we expect to see steady growth as security
concerns continue to be challenged around the world.

In the past 55 years, Deansteel has matured from a small sheet metal
shop to a production facility that encompasses more than 138,000 square
feet, and is equipped with some of the most modern fabricating equipment
available. Deansteel maintains a stock inventory of 4,000 doors and more
than 20,000 frame components to supply to our distributors.

While the company has experienced growth far beyond our founder’s
expectations, the management and employees at Deansteel have retained
Joseph Dean’s
original commitments to quality craftsmanship, honest business practices,
and the belief that without our customers we would not be here.
